UNITED STATES PATENT OFFICE. I CHARLESI'IOFF, OF CINCINNATLVOHIO. BARREL-HOOP.

Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed October 28, 1905. Serial No. 284,859.

To all whom it may concern:

Be it known that I, CHARLES HOFF, a citizen of the United States of America, and a residentof Cincinnati, in the-county of Hamilton and State of'Ohio, have invented certain new and useful Improvements in Barrel-Hoops, of which the following is a specification.

This invention relates to improvements in devices for retaining hoops or bands on barrels, kegs, tubs, churns, and the like; and it consists in'a flat metal hoop or band having intermediate its longitudinal edges aseries of arrow-head or triangular shape stops or projections on its inner face, such stops comprising uncut indentations or im ressions made in the outer face of the metal and retreating or becoming gradually deeper the thickness of the metal from the point to the base of the'triangle and said point being directed toward the bilge edge of the hoop, whereby the hoop is provided with uncut. sloping projections or spurs on its inner face to enter and anchor or embed themselves into the face of the barrel and resist accidental removal or slipping from place when once the hoop is properly driven on the barrel.

In the single sheet of drawings, forming a part of this specification, Figure 1 is a pers ective view of a barrel-hoop embodying t erein m invention; Fig. 2 an elevation of a barre having its hoops provided with I my improvement; Fig. 3, elevation of a fragmentary portion of my hoop, showing the inner face thereof; Fig. 4, an elevation showing a fragmentalg ortion of the outer face of my hoo an ig. 5, a vertical section taken on t e dotted line mm of Fig 4, but showing a sectional portion of a wooden stave to bring more clearly to view the action of the hoop retainer or anchor in its embedding position in the face of the stave.

In the views, 1 represents an ordinary barrel-hoop, made of metal and of the size and she; e to suit its position'on the barrel,

' and 2 in 'cates each one of a series of retainer formations made in the hoop intermediate its circumferential edges and projecting from the inner face of the metal to make embedding contact with the face of the barrel and to thereby resist accidental removal or slip- I ping from place in holding the ,staves and the vessel together or intact. These retainer devices or formations are constructed thus: An uncut indentation of substantially triangular or arrow-head shape is made or impressed, by means of a suitable tool, in the face of the hoop, thereby striking up or throwing the metal backward into a likeshaped projection on the rearvface of the hoop, none of the metal being cut away or cut through to weaken the hoop, but the same remaining intact. The body portion 3 of the retainer retreats or slopes backward from the point or apex of the triangle to its base 4, and the latter is preferably curved or concaved in outline and beveled to rovide a tapering walled cavity 5 on the bac of the hoop, into which cavity the fibers of the wooden stave A crowd or bury themselves, as seen in \Fig. 5, when the hoop is driven home and the retainer embeds or anchors the hoop,) and it slopes or bevels upward toward the concave base at its opposite end on the back of the hoop, so that when the hoop is driven into place the said point substantially plows into the wood to guide and bury thejproj ecting uncut beveled base, which forms an effectual stop to resist any accidental slipping of the hoop from place on the barre but permits the forcible with drawal of the hoop without material injury to the barrel.

I claim A sheet-metal barrel-hoop having on its inner face one or more equilateral-triangleshape stops each comprising an uncut re treating impression made in the face of the hoop intermediate its longitudinal edges, the apex or point of the triangle lying in the direction of the bilge edge and the base of the same being concaved or curved and bev- "eled toward said point, whereby, when the tion in the stave with \the whtiguous fibers I V Signed at Ohio, ;this 21st day of thestave crowded into the said eoneaved or curved and beveled base and resisting the accidental slipping of the 1100, item place a of 0mm; 1905. I

HDFF.

but permitting the forcible with wnlef the I hoop without material injury to the ban-e1, JOHN Joins, substantially as set forth.
